Water Luo Fist had an interesting history. According to Luo Xu, there was a river called "Water Luo" in the Heavenly Devil Mountain.
There was a story told by the villagers along the river:
A long time ago, there was no river in the Heavenly Devil Mountain. One day, the stars gathered at the sky and started pouring water from above. The water flowed to the ground and formed into a river. That was the origin of the Water Luo River.
When Luo Xu crossed the river on a boat, he saw the reflection of the stars on the surface and was inspired to create the Water Luo Fist.
Luo Xu had told Zhang Ruochen to return to the Heavenly Devil Mountain and paid the river a visit.
He thought Zhang Ruochen might be able to see different things through the river.
"That Water Luo River is not an ordinary river. Perhaps it was gifted by the other universe that we never know," Zhang Ruochen commented.
